FOLDING SUPPORT.

Specication of Letters Patent.

Application filed .Tune 11, 1920. Serial No. 388.201.

To all 107mm. t may concern:

Be it known that I, HUGO SGHEID, a citizen of Germany, residing at NewYork city,

in the county of New York and State ofy New York, *have invented certainnew and useful Improvements in Foldmg Supports,

"fully described and represented in the following specifica-tion and theaccompanying drawings, forming a part of the same.

This invention relates to folding supports, and has foran object toprovide such a support for use in connection withtrack-way or cable-wayconveyers.

lhen my invention is used in connection f with conveyers it provides asupport for the conveyer-way which may be proJected over a railroad,road or water-way `when the conveyer is in use in loading or unloadingrailroad cars, wagons or boats, and may be folded so as not to obstructthe passage of vehicles or boats when the conveyer is not in use.

Further objects and advantages of my invention will. be pointed out inconnection with a detailed description of the specific embodiment of theinvention which is shown in the accompanying drawings; in which- Figure1 is a side elevation of an end support for a conveyer cable showing infull lines the boom in operative position,and in dotted lines the boominbalanced position, and in dots and dashes the boom is folded position;

Fig. 2 is a front elevation showing the` boom in operative position andshowing a part of the boom broken away;

Fig. 3 is a fragmentary side elevation showing the arrangement of theropes for elevating the slides;

Fig. 4 is a plan view showing a portion of one of the uprights and ofthe cross-tie broken away;

Fig. 5 is an enlarged detail side elevation showing one of the slidesand one of the catches; and y Fig. 6 is a similar front elevation of theparts shown vin Fig.- 5, with the boom removed.

The structure illustrated in the drawings is used as an end support fora conveyer cable to be'used yin loading or unloading boats or' vehicles.The two uprights 10 are erected near the side of a water-way or highway.`The uprights 10 are connected by a cross-tie 11. Bracing 12 extendsrearwardly from each upright. The space between the uprights 10 isleftopen 'to afford an unobstructed passage for the conveyer. V

On each of the uprights 10 is a slide or carriage 14. VEach slideconsists of two Side plates 15 between which extend spacer bolts 16.About the bolts 16 are placed sleeves or rollers18 to facilitate themoving of the slides upon the uprights, (Figs. 5, 6).

The boom 19 consists of two side Apieces 20, the cross-piece 22, andbracing 23. Each of the side pieces 2O is hinged to one of the slides 14by means of a bolt 21.

Two braces 24 connect the outer portion of the boom with the lowerportion 'of the uprights. Each brace 24 is hinged at one end by abolt 25to a bracket 26 attached to one of the uprights below one of the slides.14, and is hinged at the other `end by a bolt 27 to a bracket 2S uponthe lower side of one of the side pieces 20 of the boom 19.

Each upright is provided with a Spring catch 29 adapted to engage aprojection 30 on its slide 14, (Figs. 5, 6). Cords 31 (Fig. 2) areprovided to trip the catches 29 to release the slides. y

Each slide 14 is provided with a bail 32 to which is attached a sheave33. Two ropesorcables 34, 35 are provided for raising the slides. Thearrangement of these ropes is shown in Figs. 2 and 3. The rope 34 isattached to the cross-tie 11 and passes around the sheave 33 of one ofthe slides, over a sheave 36 upon the cross-tie, over one sheave of thedouble block 37 upon the cross-tie, and to the hoist 38. The rope 35 isattached to the cross-tie and passes around the sheave 33 of the otherslide over the other sheave of the double block 37 and is attached tothe rope 34 by a clamp or splice 39. p

A rope 40 is attached near the outer end of the boom 19, passes over thesheave 41 and 42 on the cross-tie 11, and thence to the hoist 38.

The conveyer cable 43 is attached to the cross-member 22 of the boom 19.A conveyer 44 is mounted upon the conveyer cable 43 in the known manner.The ropes for raising and lowering the conveyer 44 and for causing itstravel along the conveyer ca- Paten-ted Dec. 7, 1920.

ble 43 are not shown in the drawings, as they form no part of thepresent invention.

If desi'red,'a sheave 45 may be mounted near the inner end of the boom19 above the conveyer cable 43.

lThe operation of the device described is as follows :When the catchesare released and no strain is placed on either the ropes 34, 35, or therope 40, the boom will assume a balanced position in which it extends atan acute angle from the uprights 10, as shown by the dotted lines A inFig. 1. The boom is moved frombalanced position to working position bydrawing in the ropes 34, 35, by means of the hoist 38 until the slides14 engage and are held by the spring catches 29. The boom and bracesthen occuply the position shown by the heavy lines in Fig. 1 and shownin the other drawings. While the boom is in this position, it forms arigid support for the conveyer cable, and the conveyer 44 may beoperated to load or unload boats or vehicles on the water-way orhigh-way beside the uprights 10. As there is no bracing between theuprights 10, an

open space is provided for the operation of the conveyer 44. 1

When the loading or unloading is completed, the boom may be foldedso asnot to project over the water-way or highway,and

thus to leave an unobstructed passage for boats or vehicles. This isaccomplished by releasing the catches 29 by a pull on the trip cord 31.The slides will then slip down the uprights 10, and the boom will assumethe balanced position shown at A in Fig. 1. The boom is drawn frombalanced position to folded position, shown by the dotted lines B inFig. 1, by drawing in the rope 4() by means of the hoist 38.

`When it is desired again to to use the conveyer, the rope 40 isreleased and the boom reassumes the balanced position A from which it isdrawn into working position in the manner described.

The pulley 45 keeps the conveyer cable 43 taut when the boom is foldedand during the folding operation and thus keeps the cable off the groundwhen the boom is folded.

Many changes may be made in the specific device described withoutdeparting from my invention, and my folding support may be used forother purposes than that referred to in the description of this device.It may, for example, be used in connection with track-way conveyers andfor other purposes.

What is claimed is:

1. A folding support for conveyer-ways, comprising two spaced uprightsbetween which the conveyer passes, slides upon said uprights, a boomhinged to said slides and acting as a support for the conveyer-way, andbraces hinged to said boom and hinged to said uprights.
